    • Developments in acoustics for studying wave-driven boundary layer flow and sediment dynamics over rippled sand-beds 

      Thorne, Peter D.; Hurther, David; Cooke, Richard D.; Cáceres Rabionet, Iván; Barraud, P.A.; Sánchez-Arcilla Conejo, Agustín (2018-08)
      Article
      Accés obert
      The processes of sediment entrainment, transport, and deposition over bedforms are highly dynamic and temporally and spatially variable. Obtaining measurements to understand these processes has led to ongoing developments ...

      Accés obert
      A large-scale wave flume experiment has been carried out involving a T¿=¿4 s regular wave with H¿=¿0.85 m wave height plunging over a fixed barred beach profile. Velocity profiles were measured at 12 locations along the ...

    • Measurements and modeling of sediment transport during offshore and onshore bar migration 

      Grossmann, Florian; Hurther, David; Sánchez-Arcilla Conejo, Agustín; Alsina Torrent, José María (World Scientific, 2023)
      Text en actes de congrés
      Accés restringit per política de l'editorial
      Effective design of interventions in the coastal zone (flood defense, nourishments, etc.) requires understanding of long term coastal evolution. Historically, such evolution has been difficult to model because of different ...

    • Near-bed sediment transport during offshore bar migration in large-scale experiments

      Article
      Accés obert
      This study presents novel insights into hydrodynamics and sediment fluxes in large-scale laboratory experiments with bichromatic wave groups on a relatively steep initial beach slope (1:15). An Acoustic Concentration and ...

    • Near-bed sediment transport processes during onshore bar migration in large-scale experiments: comparison with offshore bar migration 

      Grossmann, Florian; Hurther, David; Van der Zanden, Joep; Sánchez-Arcilla Conejo, Agustín; Alsina Torrent, José María (Wiley, 2023-03)
      Article
      Accés obert
